Math Problem Statement

Simplify the following expression and give your answer in index form as a single power of 2: (2^(3/4) × 2^(5/8) ÷ 2^(1/6))^4

Solution

The problem is asking to simplify the following expression and give the answer as a single power of 2:

(234×258÷216)4\left(2^{\frac{3}{4}} \times 2^{\frac{5}{8}} \div 2^{\frac{1}{6}}\right)^4

Step-by-step solution:

  1. Simplify the exponents inside the parentheses: Using the laws of exponents: am×an=am+n,aman=amna^m \times a^n = a^{m+n}, \quad \frac{a^m}{a^n} = a^{m-n} The expression inside the parentheses is: 234×258÷216=2(34+5816)2^{\frac{3}{4}} \times 2^{\frac{5}{8}} \div 2^{\frac{1}{6}} = 2^{\left(\frac{3}{4} + \frac{5}{8} - \frac{1}{6}\right)}

  2. Combine the exponents: To add and subtract these fractions, find the least common denominator (LCD). The denominators are 4, 8, and 6. The LCD of 4, 8, and 6 is 24. Convert each fraction to have a denominator of 24:

    34=1824,58=1524,16=424\frac{3}{4} = \frac{18}{24}, \quad \frac{5}{8} = \frac{15}{24}, \quad \frac{1}{6} = \frac{4}{24}

    Now, combine the exponents: 1824+1524424=2924\frac{18}{24} + \frac{15}{24} - \frac{4}{24} = \frac{29}{24}

    So, the expression inside the parentheses simplifies to: 229242^{\frac{29}{24}}

  3. Apply the outer exponent: Now raise the simplified expression to the power of 4: (22924)4=22924×4=211624=2296\left(2^{\frac{29}{24}}\right)^4 = 2^{\frac{29}{24} \times 4} = 2^{\frac{116}{24}} = 2^{\frac{29}{6}}

Thus, the final simplified expression is:

22962^{\frac{29}{6}}
